Hi Ryan,

Wondering, if you could please help provide the solution for this problem.

Thanks,

Hi Ryan,

Thanks for the response. It worked fine now. But when I pass the album name, that has more than 1 word with spaces in between, I am getting error. If I pass the name that has no spaces then it works fine.

Code I am using is: PhotoQuery query = new PhotoQuery(PicasaQuery.CreatePicasaUri("default", "Album Name"));

Hi Mahesh,

The PWA API has support for heterogeneous feeds -- different kinds of entry objects in each feed. For instance, you could have comments, photos and albums all returned as part of the same feed. I suspect what is happening here is that you are retrieving a list of albums rather than a list of photos, as the AlbumQuery class in the .NET client library generates a URL with a kind=album. You can tell for sure by looking at the generated Uri property of the query class, and retrieving that in your web browser.

Have you seen the code sample
here?:http://code.google.com/apis/picasaweb/developers_guide_dotnet.html#Li...

Here's the reference list of different kinds and which feeds they are available in:http://code.google.com/apis/picasaweb/reference.html#Kind
